On campus interview by two very nice Indian engineers They follow a standard questions sheet which is identical for every interview on that day. Basically they repeat some similar behavior questions three times, such as how you deal with controversial problem or conflict with co-workers. So prepare some different materials for same problem if you can. The two engineers replied my thank you letter but I didn't hear back from them regarding next step. SInce I only has the contact info from engineers, that won't help much if I cant get in touch with HR.
